5962-88682012A

Overview

The Texas Instruments 5962-88682012A is a dual 4-line to 1-line data selector/multiplexer belonging to the SN54HC253 series. It features 3-state outputs and operates within a supply voltage range of 2V. The device is housed in a 20-pin LCCC (FK) package, also identified as CQCC20 or CDIP. It supports an extended operating temperature range from -55°C to 125°C, ensuring reliability in harsh environments.

Feature Summary

• Dual independent multiplexing channels for signal routing
• CMOS technology with 3-state output capability
• Extended industrial temperature rating for high-reliability applications

Applications

• Military aerospace systems requiring radiation-hardened logic
• High-reliability telecommunications equipment
• Industrial control systems operating in extreme temperatures

Procurement Notes

Verify the specific package variant (LCCC FK vs. CDIP) against the datasheet revision, as suffixes may indicate physical form factor differences without altering electrical function. Confirm that the 2V minimum supply voltage meets system requirements. Ensure the 3-state output configuration aligns with bus architecture needs. Validate the -55°C to 125°C temperature range against environmental specifications.

Selection Notes

Select this component when dual 4-to-1 multiplexing with tri-state outputs is required in space-constrained military or industrial designs. The HC logic family offers compatibility with standard CMOS interfaces. Consider the LCCC or CDIP packaging options based on board layout and thermal management constraints. Verify that the 2V minimum supply voltage is compatible with the system power rails.

Part Context

This part is a military-grade version of the SN54HC253, manufactured under DoD specifications. It belongs to the broader SN54/74HC series of high-speed CMOS logic devices. The 5962 prefix indicates it is a direct-buy or military lot part, distinct from commercial SN74 variants. It provides enhanced reliability and screening compared to standard commercial equivalents.

Replacement Considerations

Direct substitutes include other SN54HC253 variants with matching package and temperature ratings. Commercial SN74HC253 parts are electrically similar but lack the military temperature and screening qualifications. Verify pinout compatibility before substitution.
